At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade.

Your mission

We are looking for a highly motivated, hands-on Integration Engineer to lead the mechanical and electrical integration of critical subsystems across our hybrid-electric aircraft platform. You will be responsible for bridging design, manufacturing, final assembly, and testing to ensure that complex systems come together seamlessly from prototype through rate production.

This is a cross-disciplinary role at the heart of aircraft development, where attention to detail, fast-paced execution, and strong problem-solving instincts are key. You’ll work side-by-side with design engineers, manufacturing, and technicians on the production floor to turn ambitious designs into high-performance, certifiable products.

Key responsibilities include but are not limited to:

System Integration & Assembly

  • Own the integration of propulsion, battery, avionics, and structural systems into the aircraft platform
  • Define and document build sequences, mechanical interfaces, fastener strategies, cable routing, and fluid line installations
  • Support and optimize aircraft-level assembly processes, from first article to full-rate production

Design Collaboration & DFM

  • Provide real-time design-for-assembly feedback to design engineering teams
  • Influence interface definitions, mounting strategies, and accessibility for maintainability
  • Drive resolution of interface issues between subsystems during development and build

Build Floor & Hands-On Support

  • Act as the technical liaison on the build floor to troubleshoot integration issues and lead root cause investigations
  • Support technicians during assembly with guidance, documentation, and process improvements
  • Ensure that integration work meets engineering intent, quality standards, and certification requirements

Process Development & Continuous Improvement

  • Create and maintain detailed work instructions, assembly drawings, and configuration documentation
  • Work with manufacturing and engineering teams to improve efficiency, reduce errors, and streamline assembly processes
  • Support integration testing and data collection during system bring-up and aircraft checkout

Your place of work will be at our office located in Torrance, CA. Some domestic travel may be required

Skills & Requirements

  • Bachelor’s degree in Mechanical, Aerospace, or Systems Engineering (or equivalent experience)
  • 3+ years of experience in aerospace, automotive, or advanced manufacturing environments
  • Strong understanding of mechanical systems, fasteners, electrical connectors, harnessing, and fluid systems
  • Proficiency in CAD (e.g., NX, CATIA, or SolidWorks) and interpreting engineering drawings with GD&T

These Qualifications Would Be Nice To Have

  • Experience in aircraft or vehicle final assembly, particularly with electrical and fluid system integration
  • Exposure to configuration control, hardware traceability, and change management
  • Demonstrated ability to work cross-functionally in high-speed development programs
  • Experience with electric propulsion, high-voltage systems, or thermal integration
  • Comfortable working hands-on with tools and hardware in a production environment
